At last night’s Ambassadors of Rock Tour featuring Willie Nelson at the Hard Rock Times Square, which was held to support the Sustainable Biodiesel Alliance, actor and environmentalist Woody Harrelson showed up, but he wasn’t much in the mood for talking up the night’s cause, let alone chatting about his good friend, actor Owen Wilson, whose recent failed suicide attempt made headlines around the world.

“We’re here because we’re all here to support biodiesel," Woody explained to OK!. "Hopefully we can change the society from a petrol to a biodeseil society.”

And when asked what the best thing anybody can do to help the environment is, he said, “The simplest thing is to buy organic.”
